I received a call from the Vet.
My little Red Sided female passed away before surgery could be done.
The blockage was in the colon. He said it was a hard calcified substance. I asked if it could be urates? He said no.
I'll pick her up tomorrow for a proper burial at home.
My Vet. is concerned that this situation may involve pinkies. I informed him I feed 70% worms and 30% pinkies and I haven't had problems with other snakes.
At this point, what happened remains a mystery
